When you purchase a license for SimPLL we will provide you with a license code that unlocks SimPLL on the machine on which it is installed. Additionally, we will provide an extra license code for your home computer.
You can transfer SimPLL from one machine to another, to do this you uninstall the license on the first computer, send us the uninstall code and then we will send you a license code for your new installation.
Once you have purchased a copy of SimPLL, our guarantee to you is that we will keep SimPLL running on your machines. Licensing is only to prevent unauthorized use of our software, not to force you to buy extra licenses each time you change computers.
